Choose the output format by destination
WebP is a strong default for website images because it usually keeps quality high at a smaller file size.
Practical image guidance
Resize for the place the image will be used
A 1600 pixel wide export is enough for many full-width web layouts, while square profile photos often need exact dimensions such as 512 by 512.
Balance quality, file size, and compatibility
Lower quality settings can shrink photos quickly, but logos, text, and interface screenshots often need PNG to keep edges crisp.
Specific advice for PNG to AVIF
Test screenshots differently from photos
A screenshot may contain one-pixel lines, flat colors, and small text.
Confirm alpha support in your workflow
AVIF can carry transparency, but the software consuming the result must support it too.
Resize once, at export
Set the intended width here instead of repeatedly resizing intermediate images.
How it works
Choose a PNG file.
Keep AVIF selected and adjust quality if needed.
Convert, inspect edges and transparency, and download.
